This is a technique using a contrast medium to outline blood vessels. The procedure may be done in a variety of ways, depending on the indications. Examples include coronary angiography, performed in the cardiac catheterisation laboratory, by an interventional cardiologist to examine the heart for blockages; peripheral angiography, done by a vascular surgeon also performed in a cardiac catheterisation laboratory, to look for blockages in the arteries to the lower limbs. 

Stenting involves stretching a narrowed area of the artery with a small cylindrical balloon. Once the narrowing has been stretched a stent is inserted (a fine mesh cylinder usually of stainless steel) that supports that part of the artery.

Trans Oesophegeal Echocardiogram.

A medical device that uses electrical impulses, delivered by electrodes that contract heart muscles, to regulate the heart beat.

A small, battery-powered electrical impulse generator that is implanted in patients who are at risk of sudden cardiac death due to ventricular fibrillation and ventricular tachycardia.

Insertion of loop recorders that allow for ECG monitoring by your cardiologist.
